Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of damper, and more specifically, relates to a modular damper for elevator hoisting machine. BACKGROUND

[0002] The elevator hoisting machine is the power equipment of the elevator, also called the elevator main machine or elevator driving device. It converts electric energy into mechanical energy to drive the elevator car and the counterweight to move up and down in the shaft, realizing the vertical transportation of passengers and goods. It is one of the core components in the elevator system, and its performance directly affects the running efficiency, safety and service life of the elevator.

[0003] Due to the vibration noise generated during the operation of the hoisting machine, it will have a great impact on people's work and life, so when installing such equipment, a damper is generally used for damping installation.

[0004] The Chinese invention patent application with publication number CN115853961A discloses a damping device for elevator hoisting machine. By setting the shear resistance assembly, the shear resistance assembly is used to limit the shear stress applied by the top plate to the damping unit. When the elevator hoisting machine shakes during operation, the top plate moves, and the transmission member moves with the top plate. The action of the transmission member in the horizontal direction will directly have a force on the limiting sleeve, and because the elastic limiting piece is arranged between the limiting sleeve and the limiting plate, the elastic limiting piece will apply a reverse force to the limiting sleeve, thereby limiting the action amplitude of the transmission member in the horizontal direction, and further limiting the action amplitude of the top plate and the elevator hoisting machine in the horizontal direction. In this way, the top plate can be limited to apply a large shear stress to the damping unit, thereby avoiding the influence of shear stress on the damping performance of the damping unit in the prior art, ensuring that the damping device as a whole has good damping performance and has a long service life. However, the load of the above-mentioned damping device structure is fixed and cannot be flexibly matched according to needs. SUMMARY

[0054] wherein, N is a positive integer greater than or equal to 1, and the connecting module 51 is arranged between the upper damping pad 31 and the lower damping pad 32.

[0055] In view of the problem that the load of the existing shock absorber cannot be adjusted according to actual needs after installation is completed, for this purpose, the structure of the shock absorber is optimized, and the damping structure thereon is arranged as a modular structure capable of being increased or decreased, so as to realize load adjustment.

[0056] Specifically, two damping pads 3 are installed between the upper shell 1 and the lower shell 2, and then a module damping unit 5 is arranged between the two damping pads 3, the module damping unit 5 is composed of a connecting module 51 and a damping module 52, the damping module 52 is added as needed, for example, when the damping module 52 is added by 1, the connecting module 51 needs to have 2; when the damping module 52 is added by 2, the connecting module 51 needs to have 3, and so on. After such arrangement, assembly can be carried out as needed, which is very simple, without the need to customize the shock absorber, thereby saving cost.
